[Hongke Insights] How Can Real-World Road Scenarios Be Replicated in the Lab? Enhanced NMEA Playback Revolutionizes GNSS Scenario Replication Capabilities
An In-Depth Analysis of Enhanced NMEA Playback Technology. By combining messages such as GGA, GSV, and GSA with carrier-to-noise ratio data, this technology accurately recreates real-world GNSS road scenarios—including urban canyons and multipath interference—overcoming the limitations of traditional NMEA and IQ/RF recording methods, and enabling the validation of positioning algorithms for autonomous driving and the low-altitude economy.
